Will we be able to access the Libertine Lounge and the Steamworks Menagerie after the event is over or do we have to spend all or trinkets now if we want to use them?

They're usually always open. You're just unable to earn anymore, but you can always spend your tokens (and turn them in).

ah. thank you so very much for the information ❤️

:]

Good to know :D

That's good to know :) I was wondering that too. I quickly used all my trinkets a few days ago just in case it closed but now know I didn't have to :p
